The Musan Mining Complex is taking the lead in making innovations.

Its many units have produced a large amount of iron ore every day by making good use of heavy-duty excavators and rotary drills and introducing advanced blasting methods proactively.

Increasing the operation rate of heavy-duty trucks and equipment by properly carrying out their technical management, the ore transportation and earth-scrapping conveyor stations smoothly ensure the transport of iron ore and removal of earth.

The raw material supply and dust coal shops of the Chongjin Steel Plant have carried out their daily plans without fail by dovetailing the production processes and raising the accuracy in using raw materials and fuel.

The Puryong Ferroalloy Factory, too, supplies ferroalloy to iron and steel plants in time.
